Specification of Letters Patent.

Patented Dec. 13, 1910.

Application filed June 9, 1909. Serial No. 501,145.

To all whom it may concern:

Be it known that I, HUGH P. MCMILLAN, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new "and useful Improvements in \Vire Nails, of which the following is a specification.

This invention relates to improvements 1n wire nails and has particular 'reference to nails suitable for securing papers and fabrics to-the roofs and walls of wooden buildings or structures.

One object of the invention is to provide an improved construction of nail having a substantially central prong and a lura ity.

of eccentric loops formed integral y therewith and serving as a head.

Another object is to provide an improved nail comprising a plurality of loops one of which overlaps another and forms a driving head with a prong extending inwardly from said driving head, and a further object is to rovide an improved looped wire nail having recessed under sides for the escape of water from within the loop.

\Vith these and other objects in view the invention is illustrated in the accompanying drawing wherein Figure 1 is a perspective of the improved nail. Fig. 2, a plan view of the same. Fig. 3, a side elevation thereof, and Fi 4, a sectional view through a portion of 'a fabric coverin over a wooden structure with the lltllil driven therein to secure the fabric in ace.

Referringto the drawing the numeral, 1, designates one end of a strand of wire bent into the form of a loop, 2, and having a reversely-curved or bent intermediate portion, 3, from which a second 100 4, is formed. This latter loop, 4, is provi ed adjacent the intermediate portion, 3, with an out-turned or arched bend, 5, which projects over and around the said portion,-3, and from said arch or bend, 5, the op site end, 6, of the wire turns inwardly to orm the nail proper which is to be driven into the wood.

The arch or bend, 5, serves two purposes in that it acts as a head to receive the blows of a tool to drive the nail in place and it also clenches or grips the intermediate portion, 3, and prevents spreading of the loop, 4, when the nail is driven home.

The loops, 2, and, 4, are preferably slightly inclined downwardly from the intermediate side of the driving 3, as shown in Fig. 3, so that when the extreme edges will contact before the intermediate ortion and thus avoid liability of those en s springing upwardly as the said intermediate portion is driven in (place. The loops, 2,,and, 4, and interme iate portion, 3 it will therefore be seen constitute the head.

It has been found that if the loop portions of the nail are driven into continuous portion, driven,

contact with the fabric, 7, that water will accumulate therein and will gradually work into the pores of the paper fabric and rot it out around the loops. each loop with one or more outward bends, 8, forming arched recesses or openings, 9, at theinner side of the loop and by means of these openings the water may drain off.

By means of the double loop head formation the nail has a comparatively large surface in contact with the fabric so that when driven into the wood structure, 10, the paper fabric will be held close against the wood.

It is obvious that the loops need not be of a circular formation-but'ma have an angular formation and it should be understood this broader light.

Having thus described my invention what I claim and desire to secure by Letters Patent is,

1. A nail formed of a single strand of wire and having a driving prong and two loops,-one extending laterally from one rong and the other extending laterally thedrlving prong.

2. A nail formed of a sin le strand of wire and comprising a plura ity of loops one of which overlaps another and forms a driving head and havin a driving prong turned inwardly from sai head.

3. A nail formed of a single strand of wire and having a driving prong and a loop formed integrally therewith,-said loop being provided at its inner side. witha recess for the escape of water from the HUGH P. MoMILLAN. I

To avoid this I provide- "that the term loop is herein employed in"
